Performance and Emission Characteristics of CI Engine Using Cerium Oxide Nanoparticle with Water Diesel Emulsion

A detailed experimental study has been conducted to evaluate the effect of cerium oxide dose level in 15% water emulsion diesel. The emulsification method was used to produce E15. The span 80 and tween 80 were used as surfactants. The cerium oxide nano particle dose level in water emulsion diesel were 40, 60, 80 ppm respectively. The experiments were performed in a 4-cylinder, 4-stroke water cooled diesel engine at constant 1650 RPM, over different load condition. The properties such as viscosity, flash point, and calorific value were also determined as per standards. Experiments were conducted using diesel and different blends of the emulsion such as E15, E15CeO240, E15CeO260, and E15CeO280 by varying the load on the engine. Performance and emission parameter of different blends of emulsion were compared to pure diesel. Results reported that cerium oxide blended fuels substantially improve the performance and reduce harmful pollutants.
